Can't access to `sa.www4.irs.gov`

HashidaTKS commented 1 month ago

Describe the bug

We can't access some pages of sa.www4.irs.gov.

E.g. a create account page.

To Reproduce

Click "Create account" button of https://sa.www4.irs.gov/fatca-rup/reg/login/userLogin.do. Then, we get the following error. It seems that we don't have right permission for edgesuite.

ネットワークログを見ていると、 403を返しているuserLogin.doではなくて、画面遷移する前の、BjRUgDCC4へのアクセスがおかしい気がする。成功する場合は一度だけアクセスしているが、Chronosでは複数回アクセスしている。

BjRUgDCC4、minifiyされたただのスクリプトファイルだった。受信できているし問題なし。

cefsample v124と同じヘッダーをキャッシュ部分以外再現したが、やはりエラーになる。

access_cef124sample.json access_chronos_5.json
